This invention relates to improvements in rotary fluid motors, and particularly 'to explosive motors.

One object of the invention is topr'ovide' a rotary motor which is driven bygases exploded outside of the motor.

Another object is to provide a motor in which .gas is forced under pressure continuously, this pressure being intermittently admitted to an explosion chamber in which it is exploded and intermittently discharged to the rotors of the motor.

Other objects and advantages will be apparent from the following description, when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is a side elevation of a motor made inaccordance with the inventions Fig. 2 is an end elevation. Fig. 3. is a top plan view. Fig. 4 is a vertical section on the line 4-4 ofFig. 1. Fig. 5 is a vertical section on the line 4. Fig. 6 is a vertical transverse sectional View on the line 66 of Fig. 3.

Referring particularly to the accompany.- ingdrawings, 10represents a suitable base which carriesacasing 11, this casingbeing provided with the usual heat radiating fins 12. In each end of the casing are disposed the sleeves 13 which are externallythreaded at 14 for engagement with threads in openings in the end wall of the casing and the internal threads 15. Disposed within each of these sleeves is a sleeve16 having the inwardly beveled end 17 which receives the cone 18 of the shaft 19. This beveled face 17 has a pluralityof pockets 17 which are filled with graphite to reduce the friction between the sleeve 16 and the cone 18. This sleeve 16 has a reduced outer portion 20 on which is disposed a packing ring 21, a threaded sleeve 22 being screwed into the Specification of LettersPatent.

ring 21. Screwed onto the outer projecting portion of the sleeve 22is a locklnut23 which bears against the casing wall and locks the bearing rings against rotation. Keyed on each of these shafts 19 is a rotor 24 each being provided with the spiral ribs 25 which start one circumferential line centrally of the length of .the rotor. and "extend in opposite directions toward the ends of the rotor. The ribs of one rotor mesh with the ribs ofthe other rotor, and form, in effect, spiral gearing.

Secured to one side of the casing is a chamber 26 which is disposed in an upright position, asclearly shown and'is provided with a passage 27 in the lowerportion there of which leads to an ejector nozzle 28 disposed to discharge between the rotors on the line of emanation of the ribs. In the upper end of the chamber 26 is screwed a plug 28 which has anintake opening 29 in one side, and a longitudinal bore 30 extending therethrough. Extending through this bore 30 is a stem 31 of a valve 32 which is seated: against the beveled face 33 at the inner end of the plug 28. A similar plug 34 is screwed into thelower end of the chamber and ineludes a portion of the passage 27. The. stem 35 of the valve 36 is disposed through this plug 34, said valve being seated in a similar manner to the valve 32. On the outer end of the stem 31 is arranged a circumferentially grooved sleeve 37, a cup washer 38 being disposed below the sleeve and receiving the upper end of a coiled spring '39 disposed aroundthe ste1nj31. A jam nut 40 is engaged on the upper end of the stem and bears against the sleeve 37. The lower end of the spring 39 rests in a circumferential groove 41 formed on the plug '28 and normally holds the valve 32 against its seat. A similarly formed and mounted spring 42 is mounted in connection with thest'em 35 and a sleeve 43 n1ounted on said stem. Extending vertically upward and downward from the rear of the chamber 26 are the bracket arms 44 and 45, the extremities of which are apertured and disposed respectively opposite the sleeves 38 and 43. Pivotally mounted on the upper arm 44 is a crank arm 46 the portion 47 of which is forked and straddles the sleeve 37 within the groove thereof, while the arm 48 of the lever extends downwardly to a point opposite the center of the chamber,

' roller 51 disposed in the valves and to one side thereof and carries a roller 49. The lower arm 45 also carries a crank 50 which has one of its arms engaged with the sleeve 43 and the other provided with a line with the roller 49, and atthe other side of the chamber. shaft 52 extends through the center of the brackets from which the arms 44' and 45 extend, and carried on this shaft, at points to engage the rollers 49 and 51am cams 53 and 54. Th'esecams are so arranged on the shaft that they rock the arms 46 and 50 to open 32 and 36 in quick succession, the valve 32 being opened ahead of the valve 36. In the opposite side of the casing 11 is an exhaust outlet- 55.

The shafts 19 extend a considerable distance beyond both ends of the casing 11 and are incased by the housings 56 and 57. The portions of the shafts 19 within these housings are formed with the oil grooves 58 which receive oil from the oil cups 59. The oil passes from oneshaft to the shaft below by meansof a vertical passage 60 formed in the housing.

interiorly grooved sleeves 61 and are also provided with circumferential grooves 62, metal rings 63' being forced into the registering grooves to prevent the escape of oil longitudinally from the housing. The housing 57 carries a bracket 64 in which are mounted the shafts 65r and 66. The shaft 65 carriesa .pinion 67 on one end which meshes with a pinion 68 carried by the adjacent end of the upper. shaft 19. On the other end of the shaft 65 is ear meshing with a gear 70 carried by the shaft 66. The shaft 66 is disposed in line with the shaft 52 and is connected therewith by means of a flexible coupling 71. This gearing is arranged to drive the shaft 52 for rotating the cams 53 and 54 so that the crank arms 48 and 50 will be rocked.

' In the operation of the engine, gas is admitted to the intake port 29, being forced thereinto directly from the carbureter or from a storage, as desired, but in a continuous stream under constant pressure. Assuming that gas enters the combustion chamber at a pressure of fifty pounds and is exploded, the inlet valve will close by the force of the explosion, if the spring does not close it instantly. When the gas has exploded the pressure rises to approximately two hundred pounds. The outlet valve 36 will open just at the instant of the explosion and permit theexploded gases to issue from the chamber, through the nozzle 28,

and impinge on the spiral ribs of the "rotors the rotors away from each other as will be understood.

The cycle of the engine is so quick that it due to the rapid sucvalves 32and 36, and the continuous flow of gas under pressure." It will also be noted that the device is self-scavenging due to the conditions above entirely rid of burnt gases when a new. charge of unexploded gas is admitted to the chamber.

What is claimed is:

1. In a rotary motor, the combination that the combustion chamber iswith a casing, of rotors mounted therein on parallel axes and having inter-engaging ribs thereon, adjacent the point of inter-engagement of the ribs and constructed and arranged to convey the gas passing therethrough to the ribs on the said rotors independently and simultaneously, and means for opening the said passage intermittently and in rapid succession. I i

2. In a rotary motor, the combination with a casing, of rotors mounted therein on parallel axes and having inter-engaging ribs thereon, the said casing being provided with chambers at the ends ofthe rotor and an exhaust port in communication with said chambers and means for injecting gas under pressure into said casing against the said ribs, the said ribs being constructed and arranged to convey the gas to the said chambers upon the rotation of the rotors.

3. In a rotary motor, the combination With a casing, of rotors mounted therein on parallel axes, each of said rotors being provided with two sets of helical ribs extending in opposite directions from a centrally located circumferential line, the said casing being provided with chambers at the ends of the rotors, and an exhaust in communication with said chambers, means for injecting gas under pressure into the casing and against the-ribs on the rotors in alinement with the said circumferential lines thereon, whereby the rotors will be actuated and the ribs will convey the gas to the said chambers.
